D -- AMENDMENT TO SYNOPSIS FOR O&M SERVICES TO SUPPORT THE GOV''T OWNED 5ESS DIGITAL SWITCHING SYSTEM

The Commerce Business Daily Submission No. 50S3R1 posted on July 19, 2001, announcing SOL N00421-01-R-0306 for operations & maintenance services to support the government owned 5ESS Digital Switching System for Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, Maryland, Information Management Department (IMD), is amended to reclassify the solicitation as a sole source requirement to Verizon Federal. A sole source acquisition is required because the System Signaling Seven (SS7) networks that are necessary in order to provide the operations & maintenance services to the 5ESS Digital Switching System are proprietary to Verizon.
